I get that alot, and it is not from my side (sadly for SE), I have been checking my connection even during the game and the issue seems that I stop receiving signal from them, problably to compensate the surgence of other players that come near me with a leve going on and they pass through me with their leve also on and in that point the moment I see them and I start to see their leve mobs it's R0 time, resulting in near death (Rarely) or death (most of the times).
But further on, the issue seems that the game isn't still stable to allow "possibly" a large group of players solo or in a party doing or spawning leves at the same time. The moment I set foot in one of those places game crashes or I get dc, in all those cases its a median of both (50/50).
